Installing and removing VNC 5.x¶
These instructions explain how to install VNC 5.x on legacy AIX computers.
VNC Connect (version 6+) is not available for AIX.
You will need a valid license key. You may have an historic VNC 5.x Personal or Enterprise key, but if not then you will need to purchase a new VNC Connect Enterprise subscription. A license key for VNC 5.x is made available from the Deployment page of your RealVNC account.
Upgrading to VNC 5.x¶
If you are upgrading from an earlier version of VNC 5.x, installation should be seamless. You do not need to stop VNC Server, and any configuration changes you have made will be preserved. You are informed if you are required to apply a new license key.
You cannot upgrade from VNC Enterprise Edition 4.x. You must first remove it. To do this:
If you have a valid support and upgrades contract, preserve your license key by copying
/etc/vnc/licensekeyto a safe location. If you do not have a valid support and upgrades contract, you need take no action; you will need to obtain a new license key anyway.
To find out whether you have a valid support and upgrades contract, run the command
vnclicense -list. A contract is typically valid for one year from the date of issue of the license key, so in the following example until 18th November 2016:
